Question

In which of the following decomposition of rocks take place with changes in the chemical constituents of rocks?

Options

• Inorganic Weathering

• Chemical Weathering

• Organic Weathering

• Physical Weathering

Answer 1

Chemical Weathering

Explanation:

Chemical weathering involves the decomposition of rocks where there are changes in the chemical constituents of the rock. This process occurs when minerals in the rock react with chemicals in water, air, or other substances. For example, oxidation, carbonation, and hydration are types of chemical weathering where minerals like iron in rocks react with oxygen or carbon dioxide, changing the rock’s composition. This is in contrast to physical or mechanical weathering, where rocks break down without any chemical changes.
